Most cicadas go through a life cycle that lasts 2–5 years. Some species have much longer life cycles, such as the North American genus, Magicicada, which has a number of distinct "broods" that go through either a 17-year (Brood XIII), or in some parts of the region, a 13-year (Brood XIX) life cycle [51] The long life cycles may have developed ...
